Experience is known to affect the development of ocular dominance maps in visual cortex, but it has remained controversial whether orientation preference maps are similarly affected by limiting visual experience to a single orientation early in life. Here we used optical imaging based on intrinsic signals to show that the visual cortex of kittens reared in(More)
In the mammalian visual cortex, key neuronal response properties such as orientation preference and ocular dominance (OD) are mapped in an orderly fashion across the cortical surface. It has been known for some time that manipulating early postnatal visual experience can change the appearance of the OD map. Similar evidence for developmental plasticity of(More)
BACKGROUND rs6943555 in AUTS2 has been shown to modulate ethanol consumption. We hypothesized that rs6943555 might be associated with completed suicide. METHODS We genotyped rs6943555 in 625 completed suicides and 3861 controls using real-time TaqMan Allelic Discrimination Assay. All individuals were Polish Caucasians. RESULTS We detected an association(More)
Restrictive cardiomyopathy is a rare form of pediatric cardiac disease, for which the known genes include MYH7, TNNT2, TNNI3, ACTC1, and DES. We describe a pediatric proband with fatal restrictive cardiomyopathy associated with septal hypertrophy and compound heterozygosity for TNNC1 mutations (NM_003280: p.A8V [c.C23T] and p.D145E [c.C435A]).

In the PI(3,5)P2 biosynthetic complex, the lipid kinase PIKFYVE and the phosphatase FIG4 are bound to the dimeric scaffold protein VAC14, which is composed of multiple heat-repeat domains. Mutations of FIG4 result in the inherited disorders Charcot-Marie-Tooth disease type 4J, Yunis-Varón syndrome, and polymicrogyria with seizures. We here describe(More)
In 1999, based on a single family, spondyloepimetaphyseal dysplasia (SEMD) with mental retardation (MR) was described as a novel syndrome with probably X-linked recessive inheritance and unknown molecular defect (MIM 300232). Our purpose was to search for the causative defect in the originally described family and in an independently ascertained second(More)
Loss-of-function de novo mutations in the SETD5 gene, encoding a putative methyltransferase, are an important cause of moderate/severe intellectual disability as evidenced by the results of sequencing large patient cohorts. We present the first familial case of a SETD5 mutation contributing to a phenotype of congenital heart defects and dysmorphic features,(More)
RAB40AL has been reported as the locus for Martin-Probst syndrome (MPS), an X-linked deafness-intellectual disability syndrome. The report was based on segregation of a missense change p.D59G with the disease in a single family and in vitro localization studies. We found the p.D59G variant by whole-exome sequencing in two patients; however, the diagnosis of(More)
RATIONALE Variants in TRIM63, including a nonsense mutation (p.Q247X), have been suggested recently to cause hypertrophic cardiomyopathy. OBJECTIVE To verify pathogenicity of TRIM63 p.Q247X detected by whole-exome sequencing in a symptomless professional sports player seeking medical advice because of a prolonged QT interval found during a routine(More)
Epileptic encephalopathies (EE) include a range of severe epilepsies in which intractable seizures or severe sub-clinical epileptiform activity are accompanied by impairment of motor and cognitive functions. Mutations in several genes including ion channels and other genes whose function is not completely understood have been associated to some EE. In this(More)
